Recently, Free Pascal (FPC) version 2.2.0 was released. This open source Pascal compiler has - since its initial release in 1993 - grown to be one of the most sophisticated open source compilers available today. Daily, more programmers discover FPC and develop their applications in Object Pascal. Specifically, the development of Lazarus has contributed to this phenomenon: Lazarus is a graphical open source IDE for FPC, with an extensive tool kit to design graphical (GUI) applications.

No and no.
Gtk2 isn't present on some KDE only distroes, and vice versa. Gtk1 is even worse.

Thank you. Glad somebody agrees.

But generally you're right. Distributing gtk2/qt apps isn't much of a problem in the "mainstream" linux desktop world.

Still doesn't solve the library version issue. You create a Qt app using the latest version of Qt 4.3. No distro I know includes that version. I think they are still on v3.x because of KDE.

So my point still stands. Using XLib (or GDI) directly as in the case of fpGUI, resolves all kinds of redistribution issues. Being a ex-Kylix developer I know all about redistribution issues and wasn't going to make that mistake again!
